Orange Hawkweed, Hieracium aurantiacum, Naturalized Minnesota Wildflower plant, Eloise Butler Wildflower Garden, Invasive

The Hawkweeds of the genus Hieracium have yellow or orange flowers that look like large dandelions, usually several in a cluster atop a stem above basal leaves or in some, alternative leaves. The Orange Hawkweed flower is about 1 inch wide or less, the plant with hairy stems and basal leaves. The plant can rapidly colonize a newly disturbed area via runners and rhizomes. The native Hawkweeds in Minnesota differ from non-natives in that the natives do not produce runners, do not have basal leaf rosettes and have branched stems. Native Hawkweeds include H. longipilum (Hairy hawkweed), H. scabrum (Rough hawkweed) and H. umbellatum Narrow-leaf hawkweed) and H. canadense (Canadian hawkweed). H. umbellatum and H. canadense are also in the Garden.
